The chamber was a sphere.
Caleb had walked sixty-three meters through concrete right angles, lead lining, and copper mesh. Then the passage opened into a shape the corridor had not prepared him for.
Twelve meters in diameter. Poured from a gray material that belonged to neither concrete nor stone, veined with darker lines that seemed random until Caleb let his eyes unfocus. The veins were lines of force. They converged at twelve points around the circumference of the sphere, each point ending in a hand-sized recess.
The marks.
Marcus walked to the center.
There was a small raised platform at the center of the sphere. Not stone. Something else. A black disc, two meters across, six inches high. The seal.
He set the working dampener case at its edge. He did not open it. He kept his attention off it.
He said: "Take your positions."
The Mimic walked the circumference.
